    • PROBLEM TO BE SOLVED: To provide a fiber-reinforced resin composition which exhibits excellent friction/abrasion characteristic, does not require the surface treatment of PPS fiber woven fabric and exhibits satisfactory adhesion to a phenol resin.
      SOLUTION: The fiber-reinforced resin composition for the sliding member is obtained by impregnating the polyester fiber woven fabric with a resol-type phenol resin synthesized from phenols containing 50-100 mol% of bisphenol A and formaldehydes by using amines as a catalyst, having a number-average molecular weight Mn of 500-1,000, as measured by the gel permeation chromatography, and having a dispersion degree Mw/Mn as a ratio of a weight-average molecular weight Mw to a number-average molecular weight Mn of 2.5-15. Alternatively, a fiber-reinforced resin composition for sliding member is obtained by impregnating PPS fiber woven fabric with the resol-type phenol resin and PTFE. A laminated sliding member is formed from the compositions.

    • PROBLEM TO BE SOLVED: To provide a fiber-reinforced resin composition requiring no surface treatment of polyester fiber textile fabrics made therefrom and capable of exhibiting satisfactory adhesion property with a phenol resin. SOLUTION: In the fiber-reinforced resin composition for a sliding member, 50-37 wt.% of the polyester fiber textile fabric is impregnated with 50-63 wt.% of a resol type phenol resin. The resol type phenol resin is synthesized from phenols, in which the molar ratio of bisphenol A is 50-100%, and formaldehyde, using an amine as a catalyst, and has a number average molecular weight Mn of 500-1,000 as measured by the gel permeation chromatography and a dispersion degree Mw/Mn, as the ratio of a weight average molecular weight Mw and a number average molecular weight Mn, of 2.5-15. The laminated sliding member is formed by laminating a plurality of sheets of the fiber-reinforced resin compositions for a sliding member and bonding them to each other. COPYRIGHT: (C)2009,JPO&INPIT
